Description

Technical Field

[0001] This invention relates to the field of polyester film production technology, specifically to a high-strength unidirectional polyester film production apparatus and its preparation method. Background Technology

[0002] Polyester film (PET film) possesses excellent mechanical properties, temperature resistance, chemical corrosion resistance, and insulation properties, and is widely used in electronics, packaging, building materials, photovoltaics, and other fields. In certain specific applications, such as photovoltaic backsheets and electronic insulation materials, films with high-strength unidirectional mechanical properties are required, i.e., high longitudinal tensile strength and relatively low transverse strength, to meet the stress requirements in specific directions. The production of high-strength unidirectional polyester film requires polyester chips for subsequent preparation. However, polyester chips inevitably contain a large amount of dust and other impurities during storage or transportation. The presence of these impurities can affect the normal production of polyester film; therefore, pre-processing recycling of polyester chips is necessary during processing.

[0003] In the prior art, such as Chinese Patent Publication No. CN118700381A, a raw material recycling device for polyester film production is disclosed, including a box body. A processing mechanism is provided on the body of the box body. The processing mechanism includes two slide bars, the outer surfaces of which are movably connected to the outer surface of the box body. Slide rods are slidably connected through both sides of the inner side of the box body. One end of one slide rod is fixedly connected to the outer surface of the slide bar on one side, and a filter cylinder is provided on the outside of the other end of the slide rod on one side. The outer surface of the filter cylinder is movably connected to the inside of the box body, and a kettle tube is slidably connected through the inside of the filter cylinder. This relates to the field of polyester film technology and solves the problem that when using existing raw material recycling devices for polyester film production, due to the different sizes of the raw materials, the recycled raw materials tend to accumulate tightly inside the collection box. This can affect the heat dissipation of the raw materials and their use after recycling, resulting in poor raw material recycling effect.

[0004] In existing technologies, when recycling polyester film chips, impurities are often removed directly from the polyester chips by setting up filter cartridges. However, due to the polyester chips being piled up and adhered together, this method often fails to achieve good recycling results with a single screening. Furthermore, washing with water requires additional drying operations to achieve the recycling of polyester chips, resulting in low integration and hindering rapid recycling production.

[0005] Therefore, we propose a high-strength unidirectional polyester film production device and its preparation method to solve the problems mentioned in the background technology, which mostly involve directly removing impurities from polyester chips by setting up filter cartridges. However, due to the accumulation and adhesion of polyester chips, this method often cannot achieve a good recycling effect in a single screening. Furthermore, water washing requires additional drying operations to achieve the recycling of polyester chips, resulting in low integration and hindering rapid recycling production. Summary of the Invention

[0006] The purpose of this invention is to provide a high-strength unidirectional polyester film production device and its preparation method, in order to solve the problems mentioned in the background art, which mostly involve directly removing impurities from polyester chips by setting up filter cartridges. However, due to the accumulation and adhesion of polyester chips, this method often cannot achieve a good recycling effect in a single screening. Furthermore, washing with water requires additional drying operations to achieve the recycling of polyester chips, resulting in low integration and hindering rapid recycling production.

A vertical swing arm is also mounted on the outer side of the extension shaft. A hopper assembly is fixedly connected to the top surface of the housing mechanism. A guide rail assembly is fixedly connected to the right side of the hopper assembly. The guide rail assembly has a longitudinal groove inside. The floating block is installed inside. A connecting shaft is installed on the right side of the floating block. The connecting shaft is connected to the vertical swing arm. A splicing support arm is installed on the top of the floating block by bolts. A ring-shaped support guide plate is fixedly connected to the side of the splicing support arm away from the floating block. A connecting frame is fixedly connected to both the front and rear sides of the support guide plate. A clamping push rod is fixedly connected to the inner side of both connecting frames. A vertically arranged vibrating support arm is also clamped and limited on the inner side of the two clamping push rods. A base plate assembly is fixedly connected to the bottom end of the vibrating support arm. An inclined dredging support rod is fixedly connected in a ring array on the top surface of the base plate assembly.

[0009] Preferably, the guide bracket is equipped with a bracket mechanism inside. There are two bracket mechanisms, and the two bracket mechanisms are installed opposite to each other in the two guide brackets. Guide sliders are fixedly connected to the left and right sides of the two bracket mechanisms. The bracket mechanism is slidably connected to the slide groove in the guide bracket through the guide sliders. The right side of the two guide sliders on the right side is connected to the splicing support arm through a rotating shaft.

[0010] Preferably, the shell mechanism has an opening on the left side, on which a raw material guide chamber is fixedly connected, and a waste outlet is provided on the right side of the shell mechanism. The height of the waste outlet is lower than that of the raw material guide chamber. A through groove is provided at the front end of the shell mechanism, and an inspection door is hinged inside the through groove.

[0011] Preferably, the inspection hatch has an observation window embedded inside. Under normal conditions, the inspection hatch is attracted to the front through slot of the housing mechanism by an electromagnet. A feeding pipe is fixedly connected to the bottom end face of the hopper assembly. The feeding pipe is inserted into the housing mechanism to the lower side and communicates with the internal space of the housing mechanism.

[0012] Preferably, the housing mechanism is rotatably connected to a conveyor roller A. There are two conveyor rollers A, and the two conveyor rollers A are rotatably connected to the left and right sides inside the housing mechanism in a linear array. A conveyor motor A is installed at the front end of the housing mechanism, and the rear output shaft of the conveyor motor A is connected to the conveyor roller A.

[0013] Preferably, a conveyor belt A is installed on the outer side of both conveyor rollers A. The conveyor belt A is used to transport waste to the waste outlet. A screen plate is fixedly connected to the inner side of the connecting support plate. There are two screen plates in total, and the two screen plates are fixedly connected to the inner side of the two sets of guide brackets in opposite directions. Both screen plates are inclined.

[0014] Preferably, the screen plates have through holes arranged in a rectangular array inside for separating impurities, and the inner top of the two screen plates are fixedly connected to side baffles. The side baffles are used to restrict the release of raw materials and impurities. The inner sides of the two side baffles are fixedly connected to electromagnetic components in a linear array.

[0015] Preferably, a comb plate is installed on the inner side of the bracket mechanism via a torsion spring. Under normal conditions, the comb plate is in a state where it is restricted by the torsion spring and is perpendicular to the inner side of the bracket mechanism. When the bracket mechanism is close to the electromagnetic component, the comb plate is in a state where it is rotated to the far end by magnetic repulsion overcoming the restriction of the torsion spring. A groove is provided on the inner bottom surface of the connecting support plate, and an extension side plate is fixedly connected to the left end of the groove extending outward.

[0016] Preferably, the extended side plate and the connecting support plate are equipped with conveying rollers B in a linear array inside, and a conveying motor B is installed on the rear side of the extended side plate. The front output shaft of the conveying motor B is connected to the conveying roller B on the left side. Conveyor belts B are also installed on the outer sides of the two conveying rollers B. The conveyor belts B are used to convey plastic raw materials into the raw material guide hopper.

[0017] This invention discloses a method for preparing a high-strength unidirectional polyester film production apparatus, comprising the following steps:

[0018] S1: Pour the polyester chip raw material to be processed into the hopper assembly at the top of the housing mechanism. The raw material enters the housing mechanism through the feed pipe at the bottom of the hopper assembly and falls to the area above the conveyor belt B.

[0019] S2: Start the control motor on the outside of the connecting bracket. The output shaft of the control motor drives the bevel gear A to rotate. The bevel gear A meshes with the bevel gear B to drive the rotating shaft assembly to rotate under the support of the bearing seat.

[0020] S3: The rotating shaft assembly drives the three guide discs to rotate synchronously. The guide discs drive the V-shaped piston swing arm to swing back and forth through the eccentrically set connecting guide shaft. At the same time, the guide discs drive the vertical swing arm to swing up and down through the eccentrically fixed extension shaft on the right side.

[0021] S4: The vertical swing arm drives the floating block to slide up and down in the longitudinal groove of the guide rail assembly through the connecting shaft. The floating block drives the splicing support arm to move, and the splicing support arm drives the support guide plate, connecting frame, clamping push rod and vibrating support arm to move up and down in sequence.

[0022] S5: The vibrating support arm drives the bottom plate assembly and the unblocking support rod of the ring array to move up and down. The unblocking support rod inserts into the polyester chips accumulated on the surface of the screen plate and physically breaks up the chips.

[0023] S6: The piston swing arm drives the guide slider to slide in the groove of the guide bracket through the rotating shaft, thereby driving the bracket mechanism to slide back and forth along the inclined guide bracket. The comb plate on the inner side of the bracket mechanism moves synchronously with the bracket mechanism.

[0024] S7: When the bracket mechanism approaches the electromagnetic component inside the side baffle, the electromagnetic component is energized and generates magnetism. The comb plate is repelled by the magnetism and rotates to the far end against the limitation of the torsion spring. When the bracket mechanism moves away from the electromagnetic component, the electromagnetic component is de-energized, and the comb plate is reset to a state perpendicular to the inner side of the bracket mechanism under the action of the torsion spring.

[0025] S8: The broken polyester chips slide along the inclined screen plate surface. Impurities in the chips fall through the through holes of the screen plate, while qualified chips remain on the screen plate surface and continue to slide. The side baffle prevents the chips and impurities from falling out from the top of the screen plate.

[0026] S9: Start the conveyor motor A at the front end of the housing mechanism. The conveyor motor A drives the right conveyor roller A to rotate, and drives the left conveyor roller A to rotate synchronously through the conveyor belt A. The conveyor belt A transports the impurities falling from the screen plate through the holes to the right. The impurities are discharged through the waste outlet on the right side of the housing mechanism.

[0027] S10: The qualified slices on the screen plate slide into the collection area formed by the groove of the connecting support plate and the extended side plate, and fall onto the surface of the conveyor belt B; start the conveyor motor B behind the extended side plate, the conveyor motor B drives the left conveyor roller B to rotate, and drives the other conveyor rollers B to rotate synchronously through the conveyor belt B. The conveyor belt B conveys the qualified slices to the left, and the slices enter the subsequent production process through the raw material guide bin on the left side of the shell mechanism.

[0028] S11: Observe the internal operating status of the shell mechanism through the observation window of the maintenance hatch; when maintenance is required, disconnect the power supply to the electromagnetic components and open the maintenance hatch for maintenance.

[0029] Compared with the prior art, the beneficial effects of the present invention are:

[0030] 1. When using this invention, the motor drives the bevel gear set, rotating shaft assembly, and guide turntable to rotate, which in turn drives the vertical swing arm, floating block, and splicing support arm to move the vibrating support arm and the unblocking support rod up and down. At the same time, it drives the bracket mechanism and the comb plate to slide along the guide bracket. This achieves the dual function of the unblocking support rod breaking up the polyester chips accumulated in the hopper assembly and the comb plate combing the polyester chips discharged through the suction pipe, so that the chips are evenly distributed on the surface of the screen plate. This ensures that impurities are fully separated through the screen plate holes. Compared with the traditional filter cartridge screening method, this invention significantly improves the impurity removal rate and chip recovery quality of a single screening. Moreover, the entire process does not require water washing, avoids the cumbersome operation of the subsequent drying step, and reduces the time loss of intermediate processes.

[0031] 2. When using this invention, the conveyor motor A drives the conveyor roller A and the conveyor belt A to operate, quickly conveying impurities to the waste outlet for discharge, avoiding the accumulation and blockage of impurities in the housing; at the same time, the side baffle prevents the slices and impurities from falling out of the screen plate during movement, ensuring the stability of the impurity discharge path, allowing impurity processing and slice screening to be carried out simultaneously, maintaining the continuity of the production process. Compared with the existing technology that requires manual cleaning of impurities, this reduces labor costs and improves overall production efficiency.

[0032] 3. In use, the qualified slices after screening slide onto conveyor belt B by their own gravity. The conveyor motor B drives the conveyor roller B and conveyor belt B to directly transport the slices to the raw material guide bin, and then into the subsequent production process. This realizes an integrated operation from raw material screening to the transportation of qualified slices to the next process. Moreover, the linkage between the electromagnetic component and the comb plate can effectively clean the slices remaining on the edge of the screen plate, reducing slice waste. The whole process does not require additional transfer equipment and drying equipment, which simplifies the production process, reduces energy consumption, meets the needs of rapid production of high-strength unidirectional polyester film, and solves the problems of low integration and unfavorable rapid recycling production in the prior art.

The height of the waste outlet 1011 is lower than that of the raw material guide chamber 101. A through groove is opened at the front end of the shell mechanism 1. An inspection door 1012 is hinged inside the through groove.

[0046] This invention discloses a method for preparing a high-strength unidirectional polyester film production apparatus, comprising the following steps:

[0047] S1: The polyester chip raw material to be processed is poured into the hopper assembly 1013 at the top of the housing mechanism 1. The raw material enters the housing mechanism 1 through the feed pipe 1014 at the bottom of the hopper assembly 1013 and falls to the area above the conveyor belt B5012.

[0048] S2: Start the control motor 601 on the outside of the connecting bracket 6. The output shaft of the control motor 601 drives the bevel gear A6011 to rotate. The bevel gear A6011 meshes with the bevel gear B6013 to drive the rotating shaft assembly 6012 to rotate under the support of the bearing seat.

[0049] S3: The rotating shaft assembly 6012 drives the three guide turntables 7 to rotate synchronously. The guide turntables 7 drive the V-shaped piston swing arm 7011 to swing back and forth through the eccentrically set connecting guide shaft 701. At the same time, the guide turntables 7 drive the vertical swing arm 801 to swing up and down through the eccentrically fixed extension shaft 8 on the right side.

[0050] S4: The vertical swing arm 801 drives the floating block 8012 to slide up and down in the longitudinal groove of the guide rail assembly 8011 through the connecting shaft 8013. The floating block 8012 drives the splicing support arm 8014 to move. The splicing support arm 8014 drives the support guide plate 8015, the connecting frame 8016, the clamping push rod 8017 and the vibrating support arm 8018 to move up and down in sequence.

[0051] S5: The vibrating support arm 8018 drives the base plate assembly 8019 and the dredging support rod 8020 of the ring array to move up and down. The dredging support rod 8020 is inserted into the polyester chips accumulated on the surface of the screen plate 3011 to physically break up the chips.

[0052] S6: The piston swing arm 7011 drives the guide slider 401 to slide in the groove of the guide bracket 301 through the rotating shaft, thereby driving the bracket mechanism 4 to slide back and forth along the inclined guide bracket 301. The comb plate 4011 on the inner side of the bracket mechanism 4 moves synchronously with the bracket mechanism 4.

[0053] S7: When the bracket mechanism 4 approaches the electromagnetic component 3013 inside the side baffle 3012, the electromagnetic component 3013 is energized and generates magnetism, and the comb plate 4011 is repelled by the magnetism and rotates to the far end by overcoming the torsion spring restriction; when the bracket mechanism 4 moves away from the electromagnetic component 3013, the electromagnetic component 3013 is de-energized, and the comb plate 4011 is reset to a state perpendicular to the inner side of the bracket mechanism 4 under the action of the torsion spring.

[0054] S8: The broken polyester chips slide along the surface of the inclined screen plate 3011. Impurities in the chips fall through the through holes of the screen plate 3011, while qualified chips remain on the surface of the screen plate 3011 and continue to slide. The side baffle 3012 prevents the chips and impurities from coming out of the top of the screen plate 3011.

[0055] S9: Start the conveyor motor A201 at the front end of the housing mechanism 1. The conveyor motor A201 drives the right conveyor roller A2 to rotate, and drives the left conveyor roller A2 to rotate synchronously through the conveyor belt A2011. The conveyor belt A2011 conveys the impurities falling from the screen plate 3011 to the right. The impurities are discharged through the waste outlet 1011 on the right side of the housing mechanism 1.

[0056] S10: The qualified slices on the screen plate 3011 slide into the collection area formed by the groove of the connecting support plate 3 and the extended side plate 5, and fall onto the surface of the conveyor belt B5012; the conveyor motor B5011 behind the extended side plate 5 is started, the conveyor motor B5011 drives the left conveyor roller B501 to rotate, and drives the other conveyor rollers B501 to rotate synchronously through the conveyor belt B5012. The conveyor belt B5012 conveys the qualified slices to the left, and the slices enter the subsequent production process through the raw material guide bin 101 on the left side of the housing mechanism 1.

[0057] S11: Observe the internal operating status of the shell mechanism 1 through the observation window of the maintenance hatch 1012; when maintenance is required, disconnect the power supply of the electromagnetic component 3013 and open the maintenance hatch 1012 for maintenance.

[0058] In this embodiment, during use, the operator first slowly pours the polyester chip raw material to be processed into the hopper assembly 1013 fixedly connected to the top surface of the shell mechanism 1. The raw material is temporarily stored in the hopper assembly 1013 and gradually flows downward. It enters the shell mechanism 1 through the feed pipe 1014 fixedly connected to the bottom surface of the hopper assembly 1013. Since the feed pipe 1014 is inserted into the shell mechanism 1 downward and communicates with the internal space of the shell mechanism 1, the raw material can be accurately delivered to the area above the conveyor belt B5012 installed on the outside of the conveyor roller B501 supported by the connecting support plate 3 inside the shell mechanism 1. At this time, due to its own particle characteristics and gravity, the polyester chips are prone to forming a state of mutual accumulation and adhesion on the surface of the screen plate 3011. If directly screened, impurities are easily wrapped by the accumulated chips and are difficult to separate effectively.

[0059] To break the stacking of slices, the control motor 601 on the outside of the connecting bracket 6 installed on the bottom surface of the connecting support plate 3 is started. After the control motor 601 is started, the output shaft set at the top starts to rotate at high speed. The bevel gear A6011 installed on the output shaft rotates synchronously with the output shaft. Since the shaft assembly 6012 is installed inside the longitudinal component of the connecting bracket 6 through the bearing seat, and the bevel gear B6013 is coaxially installed on the left side of the shaft assembly 6012, the bevel gear B6013 is in a meshing state with the bevel gear A6011. Therefore, the rotation of the bevel gear A6011 will drive the bevel gear B6013 to rotate synchronously, thereby driving the shaft assembly 6012 to rotate stably under the support of the bearing seat.

[0060] Three guide disks 7 are fixedly connected to the right side of the rotating shaft assembly 6012. The three guide disks 7 are evenly distributed in a linear array. When the rotating shaft assembly 6012 rotates, it directly drives the three guide disks 7 to rotate synchronously. A connecting guide shaft 701 is eccentrically set on the inner side of each guide disk 7. Two piston swing arms 7011 are movably installed on the outer side of the connecting guide shaft 701. The two piston swing arms 7011 are distributed in a V-shape. When the guide disk 7 rotates, the eccentrically set connecting guide shaft 701 will drive the V-shaped piston swing arms 7011 to perform reciprocating swing motion. At the same time, an extension shaft 8 is also eccentrically fixedly connected to the right side of the guide disk 7. A vertical swing arm 801 is movably installed on the outer side of the extension shaft 8. The rotation of the guide disk 7 will also drive the extension shaft 8 to rotate synchronously eccentrically, thereby causing the vertical swing arm 801 to swing up and down around the extension shaft 8.

[0061] A guide rail assembly 8011 is fixedly connected to the right side of the top fabric bucket assembly 1013 of the housing mechanism 1. The guide rail assembly 8011 has a longitudinal groove inside, and a floating block 8012 is slidably installed in the longitudinal groove. A connecting shaft 8013 is installed on the right side of the floating block 8012 through a rotating shaft. The connecting shaft 8013 is movably connected to the end of the vertical swing arm 801 away from the extension shaft 8. When the vertical swing arm 801 swings up and down, it will apply traction and thrust to the floating block 8012 through the connecting shaft 8013, causing the floating block 8012 to slide stably up and down in the longitudinal groove of the guide rail assembly 8011. The longitudinal groove of the guide rail assembly 8011 limits the movement direction of the floating block 8012 to prevent it from deviating.

[0062] A splicing support arm 8014 is detachably mounted on the top of the floating block 8012 via bolts. This bolted connection facilitates subsequent maintenance or replacement of the splicing support arm 8014. When the floating block 8012 slides up and down, it directly drives the splicing support arm 8014 to move synchronously. A ring-shaped support guide plate 8015 is fixedly connected to the side of the splicing support arm 8014 furthest from the floating block 8012. Connecting frames 8016 are welded and fixed to both the front and rear sides of the support guide plate 8015. Clamps are bolted to the inner sides of both connecting frames 8016. The push rod 8017 has adjustable clamping force. The inner side of the push rod 8017 clamps and limits the vertically arranged vibrating support arm 8018. Through the clamping action of the push rod 8017, the vibrating support arm 8018 can be stably fixed inside the connecting frame 8016, and the installation position of the vibrating support arm 8018 can be easily adjusted according to actual needs. Therefore, when the splicing support arm 8014 moves, it will sequentially drive the support guide plate 8015, the connecting frame 8016, the push rod 8017 and the vibrating support arm 8018 to move up and down reciprocatingly.

[0063] The bottom end of the vibrating arm 8018 is fixedly connected to the base plate assembly 8019. The base plate assembly 8019 is a disc-shaped structure. On its top surface, multiple inclined unblocking support rods 8020 are welded and fixed in a ring array. The inclination angle of the unblocking support rods 8020 is designed to better insert into the piled polyester chips. When the vibrating arm 8018 moves up and down, the base plate assembly 8019 will drive the unblocking support rods 8020 to move up and down synchronously. The unblocking support rods 8020 are inserted into the interior of the polyester chips piled on the surface of the screen plate 3011, which physically disperses the chips that are stuck together, separating the large piled chips into small dispersed states, creating conditions for subsequent impurity separation.

[0064] Meanwhile, the splicing arm 8014 is also movably connected to the guide slider 401 via a rotating shaft. The guide slider 401 is fixedly connected to the left and right sides of the bracket mechanism 4. The bracket mechanism 4 has two locations, which are installed opposite each other inside the two guide supports 301. The guide supports 301 are fixedly connected to the inner side of the two connecting support plates 3, and there are four locations in total. Each pair of horizontally adjacent guide supports 301 forms a group and is arranged opposite each other. The guide supports 301 has a groove inside, and the guide slider 401 slides exactly in the groove. Therefore, when the splicing arm 8014 moves up and down, it will apply a force to the guide slider 401 through the rotating shaft, causing the guide slider 401 to slide along the groove trajectory in the groove of the guide support 301, thereby driving the bracket mechanism 4 to make reciprocating sliding motion along the inclined guide support 301. The inclined angle design of the guide support 301 can match the natural sliding direction of the slices and improve the combing effect.

[0065] A comb plate 4011 is movably mounted on the inner side of the bracket mechanism 4 via a torsion spring. The torsion spring has elastic restoring characteristics. Under normal conditions, the comb plate 4011 is kept perpendicular to the inner side of the bracket mechanism 4 by the elastic constraint of the torsion spring. When the bracket mechanism 4 slides back and forth along the guide bracket 301, the comb plate 4011 moves synchronously with the bracket mechanism 4. Its comb teeth contact the polyester chips on the surface of the screen plate 3011, further combing the dispersed chips and adjusting the unevenly distributed chips into a uniform and flat state, ensuring that each chip can be fully exposed on the surface of the screen plate 3011, avoiding the impurities from being wrapped and unable to be separated due to chip overlap. Through the dispersing action of the unblocking support rod 8020 and the combing action of the comb plate 4011, the polyester chips no longer pile up and stick together, and the impurities can be separated smoothly through the through holes on the screen plate 3011, significantly improving the recovery effect of a single screening.

[0066] Example 2

[0067] like Figures 1-5As shown, an observation window is embedded inside the maintenance hatch 1012. Under normal conditions, the maintenance hatch 1012 is attracted to the front through slot of the housing mechanism 1 by an electromagnet. A feed pipe 1014 is fixedly connected to the bottom end face of the hopper assembly 1013. The feed pipe 1014 is inserted downward into the housing mechanism 1 and communicates with the internal space of the housing mechanism 1. A conveying roller A2 is rotatably connected inside the housing mechanism 1. There are two conveying rollers A2, and the two conveying rollers A2 are arranged in a linear array and rotatably connected to the left and right sides inside the housing mechanism 1. A conveyor motor A201 is installed at the front end of the housing mechanism 1. The rear output shaft of the conveyor motor A201 is connected to the conveyor roller A2. Conveyor belts A2011 are installed on the outer sides of the two conveyor rollers A2. The conveyor belts A2011 are used to convey waste to the waste outlet 1011. A screen plate 3011 is fixedly connected to the inner side of the connecting support plate 3. There are two screen plates 3011 in total, and the two screen plates 3011 are fixedly connected to the inner side of the two sets of guide brackets 301 in opposite directions. Both screen plates 3011 are inclined.

[0068] In this embodiment, during use, the polyester chips, which have been dispersed by the unblocking support rod 8020 and combed by the comb plate 4011, will slowly slide downwards on the surface of the inclined screen plate 3011 due to gravity. The screen plate 3011 has two locations, which are fixedly connected to the inner side of the two sets of guide brackets 301 in opposite directions. Its inclination angle is precisely designed to ensure that the chips have enough sliding time to complete the separation of impurities, while avoiding insufficient separation of impurities due to excessive sliding speed. During the sliding process, the impurities mixed in with the chips, such as fine dust, broken chip fragments, and small particles mixed in from the outside, will fall from the rectangular array of through holes inside the screen plate 3011 under the action of gravity because of their small size and light weight. The aperture of these through holes is designed to allow only impurities to pass through, while the polyester chips will be intercepted on the surface of the screen plate 3011 and continue to slide, thus achieving the initial separation of chips and impurities.

[0069] The housing mechanism 1 has two conveying rollers A2 rotatably connected inside. The two conveying rollers A2 are arranged in a linear array and rotatably connected to the left and right sides inside the housing mechanism 1. The installation height of the conveying rollers A2 is lower than the lowest end of the screen plate 3011, ensuring that impurities falling from the through holes of the screen plate 3011 can fall accurately onto the surface of the conveyor belt A2011 installed outside the conveying rollers A2. In order to realize the active conveying of impurities, a conveyor motor A201 is fixedly installed on the front end of the housing mechanism 1. The rear output shaft of the conveyor motor A201 is fixedly connected to the left conveying roller A2 through a coupling. After the conveyor motor A201 is started, the output shaft will drive the right conveying roller A2 to rotate clockwise. Since the conveyor belt A2011 is sleeved on the outside of the two conveying rollers A2, the rotation of the left conveying roller A2 will drive the left conveying roller A2 to rotate synchronously through the friction of the conveyor belt A2011, thereby making the conveyor belt A2011 move stably in the clockwise direction.

[0070] Impurities falling on the surface of conveyor belt A2011 will be synchronously transported to the right under the movement of conveyor belt A2011. A waste outlet 1011 is provided on the right side of the shell mechanism 1. The height of waste outlet 1011 is lower than that of raw material guide bin 101, and its position is aligned with the right end of conveyor belt A2011. When impurities move to the right end with conveyor belt A2011, they will be discharged from the outside of shell mechanism 1 from waste outlet 1011 under the action of gravity due to the loss of support from conveyor belt A2011. Workers can place a collection container below waste outlet 1011 to collect and process the discharged impurities in a unified manner, so as to avoid impurities from scattering in the production environment and causing pollution.

[0071] To prevent polyester chips and impurities from slipping off the top of the screen plate 3011 while sliding on it, side baffles 3012 are fixedly connected to the inner top of the two screen plates 3011. The side baffles 3012 are long strips of material, vertically fixed to the two sides of the screen plate 3011. Their height is higher than the maximum stacking height of the chips on the surface of the screen plate 3011. They can effectively prevent the chips and impurities from shifting to the sides, ensuring that the chips always slide on the surface of the screen plate 3011 and the impurities fall accurately onto the conveyor belt A2011, avoiding the waste of raw materials and the problem of incomplete impurity collection caused by chips or impurities slipping off.

[0072] During the impurity conveying process, the speed of the conveyor motor A201 can be adjusted according to the amount of impurities falling. When the amount of impurities falling is large, the speed of the conveyor motor A201 can be appropriately increased to accelerate the movement speed of the conveyor belt A2011 and prevent impurities from accumulating on the surface of the conveyor belt A2011. When the amount of impurities falling is small, the speed of the conveyor motor A201 can be reduced to reduce energy consumption. At the same time, the conveyor belt A2011 is made of wear-resistant and anti-static material, which can not only prevent impurities from being difficult to remove due to electrostatic adsorption on the surface of the conveyor belt, but also extend the service life of the conveyor belt and reduce the frequency of equipment maintenance. Through the synergistic effect of the conveyor belt A2011 and the conveyor motor A201, impurities can be quickly and stably discharged from the housing mechanism 1, without accumulating and clogging inside the housing, ensuring that the subsequent screening operation of polyester chips can continue and guaranteeing the continuity of production.

[0073] Example 3

[0074] like Figures 3-8 As shown, the screen plates 3011 have through holes arranged in a rectangular array inside for separating impurities. Lateral baffles 3012 are fixedly connected to the top inner sides of both screen plates 3011. The lateral baffles 3012 restrict the escape of raw materials and impurities. Electromagnetic components 3013 are fixedly connected in a linear array to the inner sides of both lateral baffles 3012. A comb plate 4011 is mounted on the inner side of the bracket mechanism 4 via a torsion spring. Normally, the comb plate 4011 is in a state where it is restricted by the torsion spring and perpendicular to the inner side of the bracket mechanism 4. When the bracket mechanism 4 is close to the electromagnetic components 3013, the comb plate 4011 is in a state where... The magnetic repulsion overcomes the torsion spring's restriction and rotates to the far end. A groove is provided on the inner bottom surface of the connecting support plate 3. The left end of the groove extends outward and is fixedly connected to an extension side plate 5. The extension side plate 5 and the interior of the connecting support plate 3 are equipped with conveying rollers B501 in a linear array. A conveying motor B5011 is installed on the rear side of the extension side plate 5. The front output shaft of the conveying motor B5011 is connected to the conveying roller B501 on the left side. A conveyor belt B5012 is also installed on the outer side of the two conveying rollers B501. The conveyor belt B5012 is used to convey plastic raw materials into the raw material guide chamber 101.

[0075] In this embodiment, during use, the qualified polyester chips after impurity separation in Example 2 will continue to slide along the surface of the inclined screen plate 3011, and finally slide out from the lowest end of the screen plate 3011 and fall onto the conveyor belt B5012 set in the groove opened on the bottom surface of the connecting support plate 3. The left end of the groove extends outward and is fixedly connected to the extension side plate 5. The extension side plate 5 and the groove of the connecting support plate 3 together form the collection area of ​​qualified chips, and the upper surface of the extension side plate 5 is flush with the bottom surface of the groove of the connecting support plate 3, ensuring that the chips can slide smoothly into the collection area and will not bounce and fall due to the height difference.

[0076] To achieve rapid recycling and conveying of qualified slices, multiple conveyor rollers B501 are installed in a linear array inside the extension side plate 5 and the connecting support plate 3. The conveyor rollers B501 are rotatably connected to the inside of the extension side plate 5 and the connecting support plate 3 through bearing seats, and the top surfaces of all conveyor rollers B501 are kept on the same horizontal plane to ensure that the conveyor belt B5012 can be smoothly fitted on its outside. The rear side of the extension side plate 5 located at the rear is fixedly installed with a conveyor motor B5011. The front output shaft of the conveyor motor B5011 is fixedly connected to the conveyor roller B501 located on the left side through a coupling. After the conveyor motor B5011 is started, the output shaft will drive the conveyor roller B501 on the left side to rotate counterclockwise. Since the conveyor belt B5012 is fitted on the outside of all the conveyor rollers B501, the rotation of the left conveyor roller B501 will drive the other conveyor rollers B501 to rotate counterclockwise synchronously through the friction of the conveyor belt B5012, so that the conveyor belt B5012 moves stably in the counterclockwise direction as a whole.

[0077] Qualified polyester chips falling into the collection area will naturally land on the surface of conveyor belt B5012. Under the movement of conveyor belt B5012, they are conveyed to the left. An opening is provided on the left side of the housing mechanism 1, and a raw material guide chamber 101 is fixedly connected to this opening. The inlet of the raw material guide chamber 101 is aligned with the left end of conveyor belt B5012, and the interior of the raw material guide chamber 101 has an inclined channel design. When the chips move to the left end with conveyor belt B5012, they will smoothly slide into the inclined channel of the raw material guide chamber 101, and then be conveyed through the raw material guide chamber 101 to subsequent high-strength unidirectional polyester film production processes such as melt extrusion, achieving a seamless connection from screening to subsequent production of qualified chips.

[0078] To avoid waste of raw materials due to residual polyester chips on the edge of the screen plate 3011, electromagnetic components 3013 are fixedly connected in a linear array on the inner side of the two side baffles 3012. The electromagnetic components 3013 are components that can generate magnetism when energized. Their installation position corresponds to the movement trajectory of the bracket mechanism 4. When the bracket mechanism 4 slides along the guide bracket 301 to a position close to the electromagnetic components 3013, the electromagnetic components 3013 are energized and generate magnetism. The comb plate 4011 is made of metal material with magnetic repulsion properties. At this time, the comb plate 4011 will be subjected to the magnetic repulsion force of the electromagnetic components 3013, and will overcome the elastic limitation of the torsion spring to rotate to the far end away from the electromagnetic components 3013. The rotation of the comb plate 4011 can force the residual chips attached to its surface to fall onto the conveyor belt B5012 under the action of gravity, so as to achieve full recycling of chips and reduce raw material waste.

[0079] When the bracket mechanism 4 slides away from the electromagnetic component 3013 along the guide bracket 301, the electromagnetic component 3013 is de-energized and loses its magnetism. Under the elastic reset action of the torsion spring, the comb plate 4011 returns to its normal position perpendicular to the inner side of the bracket mechanism 4, preparing for the next combing of residual slices. In addition, a through slot is opened on the front end face of the shell mechanism 1, and a maintenance hatch 1012 is hinged inside the through slot. A transparent observation window is embedded inside the maintenance hatch 1012, through which the staff can observe in real time the running status of the conveyor belt B5012 inside the shell mechanism 1 and the slice conveying. The power supply to the electromagnetic component 3013 can be disconnected when equipment malfunctions or maintenance is required, based on the conveying status and the cleanliness of the screen plate 3011. This allows the maintenance door 1012 to disengage from the electromagnet's attraction state, enabling maintenance operations to be performed. This ensures long-term stable operation of the equipment. Through the synergistic effect of the conveyor belt B5012, the conveyor motor B5011, and the raw material guide hopper 101, qualified slices can be directly transported to subsequent processes without additional transfer equipment. Unlike existing technologies, there is no need to rely on water washing followed by drying, significantly improving the integration of the device.
